Synopsis

Imaging outside the predefined and optimized FoV may enhance accessibility for interventional MRI procedures. Here we present different measures to assess the encoding capability of gradient systems in off-center regions. Different clinically establishes sequences are compared at 0.55T and 1.5T regarding their imaging capabilities beyond the predefined target regions.
